sNAP s'rovn BOLT.

devices, term a One of the main objects of the invention is to provide a bolt of simple construction and operation by means of which overlapping plates used in stove construction mag be quickly and easily secured together. further object is to rovi'de a-bolt which may bereadily applied to parts of the stove structure where it would be very inconvenient or impossible to use the ordinary stove bolt. Another object is to provide a bolt of the character stated of simple and efiicient construction which ma be readily produced at small cost. Furt er objects will appear from the detailed description.

In the drawin Figure 1 is a slde view of the bolt asapplied;

Figure 2 is a side view, partly in section, of the modified form;

Figure 3 is an inner end view ofthe bolt.

In constructing the bolt, which is preferably made of spring steel or any other suitable material, I provide a cylindrical body 1 which has its end portion threaded at 2 to receive a securing nut 3. Body 1 is split for the greater portion of its length topro- Each of these 5 forming a shoulder 6. In using the bolt I provide two overlapping plates a and b which it is desired to secure together with alined openings 0 and 0', these openings bey greater diameter than the body of the bolt. After openings 0 and 0' have been moved into substantial alinement the bolt is inserted through these openings, arms 4 being forced toward each other during insertion of the bolt and spring in apartwhen the heads 5 are positioned ad acent to the inner face of plate b. As wi be noted more clearly from Figure 3,

n the modified'form illustrated in Figure 2 I have provided each shoulder 6 with a prong -7 which is directed toward nut 3.

These studs serve to bite into inner plate I) when nut 3 is turned tightly upon the bolt so as to effectually eliminate any possibility of t bolt when tightening up the nu .What I claim is 2- 1. In a device of the character described, a body threaded to receive a nut on one end and provided at its other end with outwardly diverging resilient arms," said arms being provided at their outer ends with enlarged heads forming shoulders projecting beyond the arms for engagement with the inner surface of a sheet of material through which the bolt, is inserted. Y

2. In a device-of the character described a body threaded at oneend for reception of a securing nut, and outwardl diverging resilient arms extendingfrom the other end of the body and each provided at its outer end tendin about the arms and with a prong extending from said shoulder in the direc-,

openings, a threaded element extending from the other ends of the arms, and a nut threaded upon said' threaded element, said nut and the shoulders co-acting to clamp between them the plates.
